Table 3 Results of a hierarchical binary logistic regression analysis predicting any risky sexual behaviour as a dichotomous outcome in adolescents

From: Risky sexual behaviour among Russian adolescents: association with internalizing and externalizing symptoms

  Step 1 Step 2 Step 3 Step 4 (final model)
OR (95 % CI) OR (95 % CI) OR (95 % CI) OR (95 % CI)
Sex (Ref = Females) 2.47 (2.02–3.01)*** 2.55 (2.07–3.14)*** 1.78 (1.43–2.23)*** 1.73 (1.39–2.17)***
Age 1.66 (1.52–1.82)*** 1.62 (1.48–1.78)*** 1.57 (1.42–1.73)*** 1.51 (1.37–1.67)***
Depressive symptoms   1.04 (1.01–1.07)* 1.01 (0.97–1.04) 1.01 (0.98–1.04)
Anxiety   0.94 (0.93–0.96)*** 0.97 (0.95–0.99)** 0.97 (0.95–0.99)**
Posttraumatic stress   1.02 (1.01–1.03)*** 1.01 (1.00-1.02) 1.01 (1.00-1.02)
Externalizing symptoms    1.08 (1.07–1.09)*** 1.06 (1.05–1.08)***
Delinquent peers     1.06 (1.03–1.08)***

  1. The Step 1 analysis included significant fixed markers of risk; In the Step 2 analysis significant internalizing (depressive, anxiety and posttraumatic stress) symptoms were added to the variables included in Step 1; The Step 3 analysis added significant externalizing symptoms (conduct problems and delinquent behaviour) to the variables included in Step 2; The fully adjusted Step 4 analysis added affiliation with delinquent peers (i.e., how many of their friends were involved in risk taking behaviours) to the variables included in Step 3
  2. CI confidence interval, OR odds ratio, R2 Nagelkerke R square
